RAILFAsTENINGI Specification of Letters Patent. v Patented Aug, 29, 1911..

Application filed September 17, 1910. Serial No; 582,461.

To all whom it may concern:

Be it known thatwe, J OHN A. MOORHEAD, a resident of Sharpsburg, in the county of Allegheny and State of Pennsylvania, and JOHN PATTERSON, a resident of Pittsburg, county of Allegheny, and State of Pennsyl- Vania, have invented a new and useful Improvement in Rail-Fastenings; and we do hereby declare the following to be a full, clear, and exact description thereof.

Our invention relates to rail fastenings and particularly to a tie plate or chair con struction for holding railroad rails to metallic ties. Its principal object is to. provide an improved metallic tie plate of simple construction which will eflectively hold the rail in place on the metallic tie employed, and at the same time take all side thrust of the rail off the bolts and thereby prevent shearing of the same and the serious accidents caused by such shearing.

A further object is to provide an improved insulating device and a conducting connection to carry the current used in railway signaling between the rails.

To these ends our invent-ion consists, generally stated, in the combination with a tie plate having a plurality of lugs (preferably rectangular) on its under surface on each side of the rail base, and provided with transverse flanges adapted to receive and bear against the rail base, of a metallic tie provided with an upper horizontal flange or face, having a plurality of slots with which said lugs exactly register. The metallic tie employed is preferably of the ordinary I-beam type, although it will be understood that any type of tie which has slots in its upper surface adapted to fit the ln s on the lower face of the tie plate is within the spirit of our invention. The lugs and the slots are preferably rectangular so that the tie plate is held securely against movement on the tie in any horizontal direction, as distinguished from sloping or angular slots which necessitate the holding of the tie plate in position by means of bolts. By our invention all side or end thrust is taken off the bolts and they merely serve to hold the tie plate down to the tie and prevent its loosening by vibration during tratlic over it.

Our invention also consists in an improved insulating device comprising princi- .a rail joint.

. the rectan pally'an insulation plate and one or more metallic protecting and conducting plates for preserving the same and carrying the electric current where the device is used at In the accompanying drawings illustrating our invention, Figure 1 is a perspective View partly in vertical section and partly broken'away of a down, of' the protecting metallic basket orillustrating a modified complete rail fastening. Fig. 2 1s a perspective detail view illustratpillow plate preferably employed. Fig. 6

1s a perspective view illustrating a modification; and Fig. 7 is a detail sectional view illustrating the construction of bolt washer employed.

The rail 1 fits within the transverse flanges 2 of the tie plate 3. Thetie plate 3' is provided on its under surface with the depending rectangular lugs 4, two or more of which are preferably arranged on each side of the rail base 5. The lugs 4 fit within ular slots 6 in the upper face or flange 7 o the metallic tie 8, which is illustrated as a tie of the I-beam type.

The bolt holes 13 are arranged inside of the slots 6 in the tie 8, but outside of the rail base 5, so that the bolts 14 do not abutagainst the said rail base. Any convenient number of such bolts 14 may be employed, two being illustrated in Fig. l and four bolt holes being shown in Fig. 2. The bolts 14 are each provided with a nut 15 bearing on a washer 10 which fits overthe rail base 5. The tie plate 3 is thus securely held to the tie 8 and the rail 5 is held down within its seat 16 between the flanges 2. The tie plate 3 is also preferably provided with the exterior flanges 9, arranged outside of the flanges 2 abutting against the rail base and adapted to carry the washers 10 in connection with the said flanges 2. The washers 10 are provided with the annular portions 11 of fiber or other insulating material so that there is no metallic contact between the rail base 5 and the said washers.

In order to provide complete insulation being plate 17 and servin depending tical flanges 18 w ich are arranged along its sides to extend substantially the height of the tie plate flanges 2. Bythis means shortcircuiting of the signal current across the metallic ties is effectually prevented. We also prefer to employ in connection with the insulating plate 17 themetallic protecting within the insulating plate 17 and plate 20 ainst the bottom 21 ofthe rail base fitting ag 5, it having the side flanges 22 extending upwardly within the flanges 18. The protecting plate 20 serves as an electrical conductor or bond to carry the signal current employed in railroads between the'rails- Thus, m Fig.

4 we haveillustrated the junction 25 of the rails 26 and 27, connected by the ordinary rail joint or fish plate 28. The member 29 illustrated in Fig.4 is of a form similar to the tie 8 although it will be understood that this member also represents a rail brace of any construction em loyed where the joint is not on the tie but between the ties.

The rotecting plate henceforth termedthe hon plate 20 is also preferably provided withthe depending flanges 30 where it is employed in connection with the rail fastening illustrated in Fi 1, the flanges 30 registering over the like anges 31 of the insulatto prevent the displacement on the tie o the said insulating plate and the bond plate 20. Fig. 3 illustrates the tie plate 3 with the rou ened top face 54 which aids in holding the 0nd plate 20 in position, or in preventing rail slipping where such bond plate is not em loyed, as in street railways or the like, the bottom face 3.', being also preferably roughened to aid in gripping the tie. In'this connection, we pre er to employ also the supplementary basket plate 33 which carries within it the insulating plate 17 and the bond plate 20 as illustrated in Fig. l. The vertical flanges 34 of the basket plate 33 together with the flanges 35 serve to incase the insulating plate 17 and to protect it against surface wear and grinding from the tie plate 3. The basket plate 33 is in all respects similar in shape to the insulating plate 17,

' and the bond plate 20, and we thus provide a perfect protection for the insulating late 17, and in connection with the insulated washer 10 a complete insulation between the The basket plate 33 is preferably provided with the roughened or milled surface 33 on its bottom and also if desired its top-face, as illustratedin Fig. 5, to prevent endwise slipping of the rail and also aid by friction the means for retaining the rail against side thrust, especially where the tieemployed has a roughened surface. Where also the rail joint is on top of the tie or the basket construction of our invention is employed between ties the bond plate 20 serves as an electrical conductor between the rail ends.

In Fig. 6, we have illustrated a modification in which the basket plate 40 is of.

heavier construction and serves also as a tie plate, although the side thrust of the rails 1s here taken by the bolts 41 through the ends 42 provided with-the clips 43, which fit over the rail "base 44. Theinsulat-ing plate 45 is similar to the plate 17 above described and the bond plate 46 is similar to the plate 20 each -of said plates 40, 45, and

46 being provided with the vertical longitudinal flanges 40, 45' and 46', respectively, and having the transverse depending flanges 40 45 and 46", as shown m Fig. 6. The clip. 43 has the lower face of insulating material so that complete insulation is provided around the rail base 44.. j

In Fig. 3 the modified form of plate 50 illustrated has depending lugs 51 situated as in Fig. 1, but connected by transverse flanges 52 for bracing the same. 53 lighten the plate and the roughened surface 54 aids in gripping the rail base.

The main features of our invention consist, however, in providing a tie plate of simple construction which can be conveniently manufactured by a single rolling and shearing operation and which serves in connection with the tie to take all side thrusts off the bolts employed. This is accomplished with-v out the necessity of bending any flanges or clips over the rail .base and d1s enses en 'tirely with this and other comp icated exedients hitherto employed. The rectanguar lugs and slots each serve toprov de a double abutting or shearlng surface, and thereby great resistance to side thrusts of the rail.
